Android 如果GridView位于PopupWindow中，如何在GridView的监听器中关闭PopupWindow

我在PopupWindow a中有一个GridView a

我只想关闭弹出窗口A，如果我单击GridView A中的一个项目

现在就像当我打开结果片段时，弹出窗口会一直留在屏幕上

PopupWindow A也是从GridView B中的项目弹出的

GridViewImplement.java:
public AdapterView.OnItemClickListener mOnItemClickListener = new AdapterView.OnItemClickListener(){
   @Override
   public void onItemClick(AdapterView<?> adapterView, View view, int i, long id){

      View popupView = activity.getLayoutInflater().inflate(R.layout.popup, null);
      final PopupWindow mPopupWindow = new PopupWindow(popupView, 800, 500, true); 

      if(id != 0){

        GridView gridViewA = (GridView)popupView.findViewById(R.id.gridview_a_popup);
        GridViewAdapter gridViewAdapter = new GridViewAdapter(activity, list, true);
        gridViewA.setAdapter(gridViewAdapter);

        GridViewImplement impl =  new GridViewImplement(activity).
        gridView.setOnItemClickListener(impl.mOnItemClickListener);

        Button closeButton = (Button) popupView.findViewById(R.id.btn_popup_close);
                if (closeButton != null) {
                    closeButton.setOnClickListener(new View.OnClickListener() {
                        @Override
                        public void onClick(View v) {
                            mPopupWindow.dismiss();// here is works.
                        }
                    });
                }

      }else{
        mPopupWindow.dismiss();// here not work.

        Bundle bundle = new Bundle();
        activity.replaceFragment(ResultFragment.newInstance(),bundle,R.id.fragment_result);

      }
   }
}

因此，我将

AdapterView.OnItemClickListener

实现到GridView B

GridViewImplement.java:
public AdapterView.OnItemClickListener mOnItemClickListener = new AdapterView.OnItemClickListener(){
   @Override
   public void onItemClick(AdapterView<?> adapterView, View view, int i, long id){

      View popupView = activity.getLayoutInflater().inflate(R.layout.popup, null);
      final PopupWindow mPopupWindow = new PopupWindow(popupView, 800, 500, true); 

      if(id != 0){

        GridView gridViewA = (GridView)popupView.findViewById(R.id.gridview_a_popup);
        GridViewAdapter gridViewAdapter = new GridViewAdapter(activity, list, true);
        gridViewA.setAdapter(gridViewAdapter);

        GridViewImplement impl =  new GridViewImplement(activity).
        gridView.setOnItemClickListener(impl.mOnItemClickListener);

        Button closeButton = (Button) popupView.findViewById(R.id.btn_popup_close);
                if (closeButton != null) {
                    closeButton.setOnClickListener(new View.OnClickListener() {
                        @Override
                        public void onClick(View v) {
                            mPopupWindow.dismiss();// here is works.
                        }
                    });
                }

      }else{
        mPopupWindow.dismiss();// here not work.

        Bundle bundle = new Bundle();
        activity.replaceFragment(ResultFragment.newInstance(),bundle,R.id.fragment_result);

      }
   }
}

GridViewImplement.java：
public AdapterView.OnItemClickListener MonitorItemClickListener=新建AdapterView.OnItemClickListener（）{
@凌驾
public void onItemClick（AdapterView AdapterView、View视图、int i、long id）{
View popupView=activity.GetLayoutFlater（）.inflate（R.layout.popup，null）；

}
}否则{

activity.replaceFragment（ResultFragment.newInstance（），bundle，R.id.fragment\u result）；
}
}
}

修改代码

GridViewImplement.java:

PopupWindow mPopupWindow;

public AdapterView.OnItemClickListener mOnItemClickListener = new AdapterView.OnItemClickListener(){
   @Override
   public void onItemClick(AdapterView<?> adapterView, View view, int i, long id){

      View popupView = activity.getLayoutInflater().inflate(R.layout.popup, null);


      if(id != 0){
        mPopupWindow = new PopupWindow(popupView, 800, 500, true);
        GridView gridViewA = (GridView)popupView.findViewById(R.id.gridview_a_popup);
        GridViewAdapter gridViewAdapter = new GridViewAdapter(activity, list, true);
        gridViewA.setAdapter(gridViewAdapter);

        GridViewImplement impl =  new GridViewImplement(activity).
        gridView.setOnItemClickListener(impl.mOnItemClickListener);

        Button closeButton = (Button) popupView.findViewById(R.id.btn_popup_close);
                if (closeButton != null) {
                    closeButton.setOnClickListener(new View.OnClickListener() {
                        @Override
                        public void onClick(View v) {
                            mPopupWindow.dismiss();// here will warning need key 'final'.
                        }
                    });
                }

      }else{
        mPopupWindow.dismiss();// here not work.

        Bundle bundle = new Bundle();
        activity.replaceFragment(ResultFragment.newInstance(),bundle,R.id.fragment_result);

      }
   }
}

   public void onItemClick(AdapterView<?> adapterView, View view, int i, long id){

      View popupView = activity.getLayoutInflater().inflate(R.layout.popup, null);
      final PopupWindow mPopupWindow = new PopupWindow(popupView, 800, 500, true);

      if(id != 0){

        gridViewA.setAdapter(gridViewAdapter);

        //GridViewImplement impl =  new GridViewImplement(activity).
        //gridView.setOnItemClickListener(impl.mOnItemClickListener);// here just use a total new implement. 
        gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                    @Override
                    public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
                        mPopupWindow.dismiss();// works here.
                        Bundle bundle = new Bundle();
                        activity.replaceFragment(ResultFragment.newInstance(),bundle,R.id.fragment_result);

                    }
                });

        Button closeButton = (Button) popupView.findViewById(R.id.btn_popup_close);

                        }

        Bundle bundle = new Bundle();
        activity.replaceFragment(ResultFragment.newInstance(),bundle,R.id.fragment_result);

      }
   }
}

您可以为GridView设置OnClickListener，并添加popupWindow.disclose（）以关闭弹出窗口。基本上是这样做的：

gridView.setOnClickListener(new OnClickListener() {
  @Override
  public void onClick(View v) {
    popupWindow.dismiss();
  }
}

我的实现有点复杂。让我包括一些代码。实际上，您正在使用onItemClick方法创建一个新的MPoppupWindow对象，并且您正在放弃这个新对象。@Krish那么，我应该将“final PopupWindow”代码移到哪里呢。或者我该如何重新组织这些功能。您能将其设为全局变量吗？如果不为null，请关闭popover。@Krish当我将其设为全局变量时，它会警告“无法为最终变量“mPopupWindow”赋值”为什么
